9. It is suggested that the concentration of SP probe should be below the visually determined CGC of the lipid alone. Also, absorbance of MC species should be below 1.5 or so.
10. 1 Consequently, the gels were transparent enough to enable the measurement of visible absorption spectra of MC species added as probes.
11. Fluorescence spectrum of 1 cannot be measured in benzene because absorption bands of headgroup of 1 and benzene are almost identical.

20. It is also unknown whether this method is applicable to the perfluorocarbon amphiphile systems due to different driving forces of self-assembling: Y. Ishikawa, H. Kuwahara, and T. Kunitake, J. Am. Chem. Soc., 116, 5579 (1994).
